MT Inventory Weight

MT Inventory Weight

MT Inventory Weight adds a configurable weight system to Minecraft. Your inventory is no longer just limited by slots — every item has weight, and carrying too much can slow you down, weaken combat, and apply the Overload effect.

The mod is made for survival, RPG, and modpack gameplay where choosing what to carry actually matters.

Features

• Automatic item weights

Most vanilla and modded items receive calculated weights automatically.

• Datapack custom weights

Item weights and armor pocket values are now data-driven through datapacks.

• fzzy_config support

Configure server and client settings in-game. Server settings can update live.

• Mod Menu support

Optional easy access to config screens through Mod Menu.

• Armor pockets

Armor can increase max carry weight through pockets.

• Overload effect

Carrying too much weight applies penalties. Strength and Haste can reduce overload severity.

• HUD display

Choose between the classic sprite HUD or a simple bar HUD.

• Item tooltips

Tooltips show item weight, stack weight, armor pockets, and container contents weight.

• Backpack and shulker support

Supported containers count stored items with reduced effective weight.

• Trinkets compatibility

Equipped Trinkets items can count toward carried weight when Trinkets is installed.

• Multiplayer support

Works in singleplayer, LAN, and dedicated servers with synced server values.

• Add-on API

Developers can add compatibility through the public com.megatrex4.api.v1 API.
